Abstract

A simple, one-step mechanochemical procedure for immobilisation of homogeneous metathesis catalysts in metal–organic frameworks was developed. Grinding MIL-101-NH₂(Al) with a Hoveyda–Grubbs second-generation catalyst resulted in a heterogeneous catalyst that is active for metathesis and one of the most stable immobilised metathesis catalysts. During the mechanochemical immobilisation the MIL-101-NH₂(Al) structure was partially converted to MIL-53-NH₂(Al). The Hoveyda–Grubbs catalyst entrapped in MIL-101-NH₂(Al) is responsible for the observed catalytic activity. The developed synthetic procedure was also successful for the immobilisation of a Zhan catalyst.
